All of the episodes of this drama were supposedly released on Netflix the same day, despite that the script feels like it was written during live filming, the story is not entirely coherent & there are some character adjustments. Naturally it is for the best if one does not try to think at depth about the fake science present in this drama.

Outside of the above it's a cute little drama that doesn't have major annoyances. It's solid, fairly chill entertainment. The reason why it's only a 7 is that there is nothing outstanding either, nothing really stands out. It's just a standard kdrama with a scifi spin. (The love triangle is resolved in a fairly acceptable way and it never devolved to the swords and daggers drawn type. )
